Energy saving performance

The device allows designing applications to be compliant with the most stringent energy

saving regulations. In order to show the typical performance is achievable, the active mode

average efficiency and the efficiency at 10% of the rated output power of a single output

flyback converter have been measured and are reported in Table 9: "Power supply

efficiency, VOUT = 5 V". In addition, no-load and light load consumptions are shown in

Figure 39: "PIN versus VIN in no-load, VOUT = 5 V" and Figure 40: "PIN versus VIN in light

load, VOUT = 5 V".
